我尝试从包含3个字段和类似谓词的表单执行搜索，并且y成为此错误：＆＃34;请求处理失败;嵌套异常是java.lang.StringIndexOutOfBoundsException：字符串索引超出范围：0＆＃34;。
这将是我的控制者：
package cl.cbrtemuco.autoconsultas.controller;
import java.util.List;
import org.jboss.logging.Logger;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import cl.cbrtemuco.autoconsultas.entity.Titulos;
import cl.cbrtemuco.autoconsultas.service.TitulosService;
@Controller
@RequestMapping("/autoconsultas")
public class TitulosController {
@Autowired
private TitulosService titulosService;
private Logger logger = Logger.getLogger(getClass());
@GetMapping("/busqueda")
public String buscarTitulos(Model theModel) {
return "busqueda";
}
@GetMapping("/buscarTituloPorRsoc")
public String buscarTituloPorRsoc(@RequestParam("razonSocial") String rSocial,
Model theModel) {
List<Titulos> elTitulo = titulosService.searchTitulosByRazonSocial(rSocial);
theModel.addAttribute("titulosPorRazonSocial", elTitulo);
return "titulosPorRsoc";
}
@GetMapping("/tituloDetallesPorRSoc")
public String tituloDetallesRSoc(@RequestParam("titulosId") int idTit, Model theModel) {
//logger.info("showing form for update");
Titulos elTitulo = titulosService.getTituloRSoc(idTit);
theModel.addAttribute("titulo", elTitulo);
return "detallesTituloPorRSoc";
}
@GetMapping("/buscarTituloPorNombre")
public String buscarTituloPorNombre(@RequestParam("apellidoPaterno") String apPaterno,
@RequestParam("apellidoMaterno") String apMaterno,
@RequestParam("nombres") String nombres, Model theModel) {
List<Titulos> elTitulo = titulosService.searchTitulosByNombre(apPaterno, apMaterno, nombres);
theModel.addAttribute("titulosPorNombre", elTitulo);
return "titulosPorNombre";
}
@GetMapping("/tituloDetallesPorNombre")
public String tituloDetallesNombre(@RequestParam("titulosId") int idTit, Model theModel) {
//logger.info("showing form for update");
Titulos elTitulo = titulosService.getTituloNombre(idTit);
theModel.addAttribute("titulo", elTitulo);
return "detallesTituloPorNombre";
}
}
这将成为我的服务：
package cl.cbrtemuco.autoconsultas.service;
import java.util.List;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;
import cl.cbrtemuco.autoconsultas.dao.TitulosDAO;
import cl.cbrtemuco.autoconsultas.entity.Titulos;
@Service
public class TitulosServiceImpl implements TitulosService {
@Autowired
private TitulosDAO titulosDAO;
@Override
@Transactional
public List<Titulos> searchTitulosByRazonSocial(String rSocial) {
return titulosDAO.searchTitulosByRazonSocial(rSocial);
}
@Override
@Transactional
public Titulos getTituloRSoc(int idTit) {
return titulosDAO.getTituloRSoc(idTit);
}
@Override
@Transactional
public List<Titulos> searchTitulosByNombre(String apPaterno, String apMaterno, String nombres) {
return titulosDAO.searchTitulosByNombre(apPaterno, apMaterno, nombres);
}
@Override
@Transactional
public Titulos getTituloNombre(int idTit) {
return titulosDAO.getTituloNombre(idTit);
}
}
最后这是我的DAO，我认为这是错误：
package cl.cbrtemuco.autoconsultas.dao;
import java.util.List;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.query.Query;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Repository;
import cl.cbrtemuco.autoconsultas.entity.Titulos;
@Repository
public class TitulosDAOImpl implements TitulosDAO {
@Autowired
SessionFactory sessionFactory;
@Override
public List<Titulos> searchTitulosByRazonSocial(String rSocial) {
Session currentSession = sessionFactory.getCurrentSession();
Query<Titulos> theQuery = currentSession.createQuery("from Titulos where RazonSocial like :rSocial",
Titulos.class);
theQuery.setParameter("rSocial", "%" + rSocial.toLowerCase() + "%");
List<Titulos> titulosEncontrados = theQuery.getResultList();
return titulosEncontrados;
}
@Override
public Titulos getTituloRSoc(int idTit) {
Session currentSession = sessionFactory.getCurrentSession();
Titulos datTituloRSoc = currentSession.get(Titulos.class, idTit);
return datTituloRSoc;
}
@Override
public Titulos getTituloNombre(int idTit) {
Session currentSession = sessionFactory.getCurrentSession();
Titulos datTituloNombre = currentSession.get(Titulos.class, idTit);
return datTituloNombre;
}
@Override
public List<Titulos> searchTitulosByNombre(String apPaterno, String apMaterno, String nombres) {
Session currentSession = sessionFactory.getCurrentSession();
Query<Titulos> theQuery = currentSession.createQuery(
"from Titulos where ApellidoPaterno like :apPaterno or ApellidoMaterno like :apMaterno or Nombres like :nombres", Titulos.class);
theQuery.setParameter("apPaterno", "%"+apPaterno.toLowerCase()+"%")
.setParameter("apMaterno", "%"+apMaterno.toLowerCase()+"%")
.setParameter("nombres", "%"+nombres.toLowerCase()+"%");
List<Titulos> titulosEncontradosNombre = theQuery.getResultList();
return titulosEncontradosNombre;
}
}
最后这里是stacktrace：

答案 0 :(得分：0)
听起来你的三个参数都是空字符串。你也可以粘贴你的jsp吗？
